If Nazneen was the mother of Praveen Kumar, who was the mother of Vinod Kapoor?

In the Mahabharat series, Vinod Kapoor played the character of Duryodhan, and his mother Gandhari was portrayed by Renuka Israni. The question frames this as a relationship puzzle - if Nazneen (who played an important female role) was mother to Praveen Kumar's character, then who was the mother of Vinod Kapoor's Duryodhan. The answer is Renuka Israni as Gandhari.
